Which toxic gas is commonly produced by fire?

Hydrogen cyanide is a highly toxic gas produced during the combustion of materials containing nitrogen, such as plastics and synthetic fibers, which are often found in household items and furnishings. In the event of a fire, this gas can be released along with smoke and other byproducts of burning materials. Hydrogen cyanide is particularly dangerous because it interferes with the ability of blood to carry oxygen, leading to severe health consequences or even death with rapid exposure.

While other gases listed may also arise from different types of combustion, hydrogen cyanide is notably prevalent in fire conditions due to the common ingredients in modern-day materials. Understanding these risks is crucial for firefighter safety and emergency response strategies, as recognizing the potential hazards of toxic gases can significantly improve decision-making in fire situations.
